In this video from DesignCon 2022, Keysight’s Mike Resso refers to 224 Gbps as a “blindingly fast speed.” Ten years from now, when 224 is old-hat and commonplace, we will look back at that statement and smile at how far we’ve come since those technologically backward, archaic days of 2022. But as of today, achieving that data rate is bleeding-edge and state-of-the-art.
This video, with Mike and Samtec’s Jignesh Shah, discusses several topics related to 224 Gbps performance, including …
- What will be the technical challenges for engineers who are developing the next generation of 224 Gbps channels?
- What types of design tools will be needed to characterize and validate these channels?
- What are some new test and measurement technologies?
- What will be more important for 224 Gbps, simulation or measurement?
- What are some resources for our readers who will be driving the future physical layer systems running at 224?
If these questions pique your interest, please watch the video. Mike and Jignesh cover too much ground to type out all of the details in this blog. So hit “play” on the video link above and listen and learn.
And, since this is a joint Samtec, Keysight video, we just happen to, coincidentally, in a totally unplanned manner, mention two products that move 224 Gbps forward.
The first is Keysight’s M8050A 120 GBd High-Performance bit error ratio tester (BERT), which supports NRZ, PAM4, PAM6, and PAM8 line coding, data rates up to 120 GBd, and 1.6T pathfinding.
The second is Samtec’s NovaRay® high-density, high-performance array interconnects. NovaRay can support 224 G because of its unique BGA-style connector construction, two points of contact on each mated pin/contact, dedicated differential pairs, and shields and grounding around each differential pair.
BTW, Samtec displayed several live product demonstrations at their booth. These demos showed Samtec connector products operating at the more cost-effective high-speed internet infrastructure speed of 112 Gbps PAM4. The first, which was the coolest demo at all of DesignCon 2022 (as decided by me), shows six Samtec interconnect systems operating at 112 Gbps PAM4. Another shows a mid-board cable application, also at 112 G.

Mike also mentioned a free download of the book Signal Integrity Characterization Techniques. This book addresses the gap between traditional digital and microwave measurement technologies while focusing on a practical and intuitive understanding of signal integrity effects within the data channel.
